BINARY FLUIDS IN VYCOR - ANTICORRELATED RANDOM-FIELDS

Binary fluids in Vycor are a realization of anticorrelated random-fiel d systems. The change from uncorrelated to anticorrelated fields has a profound effect at zero temperature. At any finite temperatures an ef fective uncorrelated random field of entropic origin is generated and thus the large scale behavior is that of uncorrelated systems. The pos sible crossovers from the pure-system behavior to the eventual uncorre lated behavior and from an effective anticorrelated to uncorrelated be havior are discussed.
